  •  Not much of a problem, IMHO (1+ / 0-)

    It's easy to get something to fall where you want it to.  Ask the guys who put Curiosity on Mars.

    The hard part is doing it without just SPLAT.  Making it happen from a height of 40 meters is only slightly easier than making it happen from orbit.  I suspect the practical application of this technology will include a large launch/landing pad, say 2-3 kilometers across.  If we can hit a target 6 kilometers across the interplanetary gulf, we can certainly bring a first stage rocket (which doesn't even leave the atmosphere, really) back down to a pretty easily-targeted spot.

    •  I doubt there would need to be a single pad (0+ / 0-)

      that large in dimension - just an area with a number of pads available that the various stages can aim for as they approach and fine-tune their trajectory.

      In Roviet Union, money spends YOU.
